accents.

To all whom it may concern Be it known that I, IvEs A. MILLER, a citizenof the United States, residing at Grapeville, in the county ofV\7estmoreland and State of Pennsylvania, have invented new and usefulImprovements in Rail-Ties, of which the following is a specification.

The present invention relates to rail ties, and has for one of itsobjects to provide a reinforced plastic tie with metallic members whichare embedded therein, and which serve as additional reinforcements, andproject a slight distance above the tie to form seats for the rail, thesaid seats having associated therewith removable means for sustainingthe rails upon the seats against vertical or transverse movement.

A still further object of the invention is the pro-vision of areinforced plastic tie with metallic rail seats which have rail securingmembers associated therewith, the said seats being disposed away fromeach other and out of contact with the metallic reinforcements for thetie to prevent the short circuiting of an electric current flowingthrough the rails or from an electric conductor connected with thejoints or meeting ends of the rails.

A still further object of the invention is the construction of a plastictie which has its lower and a portion of its side faces arranged withina woven wire basket, the said basket being flush with the said sides andbottom of the tie, reinforcements for the tie being arranged thereinbetween the mesh basket, and the tie having embedded therein andprojecting above its upper or top face metallic rail seats, the metallicbasket adapted to protect the sides and bottom of the tie when the tieis tamped within the roadbed, and also adapted to prevent thedisintegration of the tie from the moisture of the roadbed.

A still further object of the invention is the construction andarrangement of metallic rail seats which are embedded within a plastictie, and which are so shaped as to provide reinforcing elements for thetie, and which, when embedded within the tie will so support themselvesas to prevent movement, with respect to the tie in any direction.

Nith the above recited objects in view, and others which will appear asthe nature of the invention is more fully understood, the improvementresides in the construction,

combination and arrangement of parts set forth in the followingspecification and falling within the scope of the appended claims.

In the drawing there is illustrated a sat-isfactory reduction of myimprovement to practice, and in which drawing:

Figure l is a sectional view on the line -m of Fig. 2, Fig. 2 is anenlarged sectional view taken approximately on the line y-g/ of Fig. l.

My improved tie is formed of plastic ma` terial which is tamped within asuitable mold. In constructing the tie, I first place in the bottom ofthe mold a substantially rectangular reticulated or mesh basket l whichis of a size and shape corresponding with that of the mold, and as aconsequence rests upon the bottom of the mold and engages the sides, andif necessary, the ends of the mold. The basket l, in all instances, hasits bottom and sides running the full length of the mold, and the upperportions of the sides, and if desired the ends of the basket are bentinwardly, as at 2, the said inturned portions or flanges being onlysufficient to receive the body of the plastic tie and to retain thesides, ends and bottoni of the said basket flush with the sides, endsand bottom of the tie. The tie which is designated by the numeral 8, isprovided, a suitable distance above its bottom, with a plurality oflongitudinally extending reinforcing rods 4f.

During the process of molding the tie I arrange within the mold,adjacent the opposite ends thereof, metallic rail seats 5, preferablytwo of the said seats being disposed at each of the ends of the mold,and these seats are adapted to have their upper faces disposed a slightdistance above the upper face of the tie, so that the rails arrangedupon the seats will not contact with the body ofthe tie. The seats 5each comprise a substantially rectangular member which provides straightsides and ends and horizontally straight bearing faces and bottoms. Thelower edges of the members 5 are formed at their corners with outwardlyeX- tending flanges 6, and these fianges prevent the vertical movementof the said members 5 when the tie is molded, while the verticallystraight sides and ends prevent either the longitudinal or lateralmovement of the said seats.

In order to reinforce the upper portion of the plastic tie 3 between andto the opposite ends of the metallic seats 5, I employ longitudinallyextending bars 26 which have certain portions of their lengths arrangedadjacent the top and corners of the tie but which are bent angularly, asat 27,'a distance from the opposite ends of the members and continuedlongitudinally, as at. 28, below the said members 5. Any numberof themem=` bers 26 may be employed, but none ot' the said members Contactwith each other nor with any of the members 5. This is important for thereason that it is not only desirable but essential that the tie and themembers arranged upon the tie shall not inter- `tere with a current ofelectricity conducted by the rails.

Having thus described the inventiongvhat I claim as new is: l

- l. f The herein described construction of ties including a plasticbody having its botto`mits sides and ends incased in a metallic meshbasket, the edges of the basket entering the said sides and ends,metallic rail seats having their lower corners formed with flangesarranged within the tie, the upper portions of the seats projectingabove the upper tace of the tie, and rail securing members for theseats.

2. A tie comprising a plastic body, a basket comprising a foraminousmetallic member arranged to receive the bottom of the tie and lying Hushwith said bottom and a portion of the sides and end of the tie, thebasket having its upper edges inturned and embedded within the tie,longitudinal reinforcing members within the tie and disposed above thebottom of the basket and out of contact with the basket, substantiallyrectangular tie reinforcing members providing rail seats arranged withinthe tie above the basket, and rail securing members associated with theseats.

3. A plastic tie yhaving metallic reinforcing members which are spacedfrom contact with each other and including rail seats having railsecuring members associated therewith and having a foraminous memberwhich is arranged iush with the bottom and ivns A. MILLER.
